Application filed May 22, 1914. Serial No. 840,836.

. and Annealing Tables, of which the following is a specification.

lhis invention relates to a table forfannealing a sheet of plate glass and the principal object of the invention is to provide the table with improved means for heating the stationary and movable sections of the table and for permitting the sections to gradually cool while the plate of glass is cooling and being pressed.

Another object of the invention is to so construct the table thatthe movable section may be held out of a position to compress the sheet of glass while the glass is being rolled and then move to a position to compress the sheet of glass after it has been rolled. y Another object of the invention is to 'provide an improved water circulating system for the movable and stationary sections:

- Another object of the invention is to provide the stationary and movable sections with means for permitting the sections to be heated by an electrically operated system.

i This invention is illustrated in the accompanying drawings, wherein- Figure 1 is a side elevation of the improved table; Fig. 2 is a top plan view of thegim; proved table; Fig. 3 is anenlarged fragmentary elevational view Fig. l fragmentary transverse sectional view throilgh the table taken along the line M of Fig. 2; Fig. 5 is a fragmentary sec- Fig. 8 is a view similar to Fig. titaken a tional view through the stationary section taken along the line 5-5 of Fig.1; Fig. 6 is a sectional view taken along; the line ,6-6 of Fig. 5; Fig. '2' is a view similar. to

Fig. 5 taken along the line 7-7 of Fig. 1i; and long the line 88 of Fig. 7. 1

-,The table provided with a base or foundation composed of supports 10 whichcarry the of such width that they mayfit'into'ihe grooves of the wheels 15: rctatahly supported by the hearing brackets 15 of the movable section The bracket of this table is built may be formed.

of the improved table pipes 39 pass so that the. bars over pit so that the water pipes may move downwardly as the movable section moves ?'over the stationary section 17 which is rigidly connected with the track.

The stationary section is formed fromv a plurality of metallic bars 18 the contacting edges of which are provided with grooves in which keys 19 fit as shown in Figs. 5 and 7. These bars are also provided with transversely extending ribs 20 provided with undercut grooves 21 to receive the dovetailed ribs 22 of the supporting bars 23. The bars are also provided with transversely extending sleeves 2a through which the securing bolts 25 pass to securely hold the bars. 18 together. Spacing strips 26 are carried by the side bars 18 of the stationary section to regulate the thickness of the glass and prevent the soft glass from being compressed beyond a desired amount. These strips may be removed and replaced by.

others so that glass of difierent thickness waterpipes 27'and Wires 28 to passthrough In order to permit the,

the bars 18 there is provided a plurality of passageways 29 which extend the full length' of the bars thus permitting the ends of'the water pipes to extend heyond the ends of the stationary section asshown in Fig l. These pipes 27 are connected with the cross heads 30 and 31 which in turn communicate with the pipes 32 and 33 respectively. 'Tliese pipes 32 and 33 lead from the inlet and outlet mains from which the pivoted pipes 34 lead, the pipes 34 being pivoted so that when the movable section moves longitudinally upon the rails 11 the end sectionsiia may move to permit of the sliding movement of the movable section.

The movable section comprises a plurality of longitudinally extending bars35 which are provided with side grooves in which the keys 36 fit and arealsoprovided with transversely extending sleeves. 37f'to receive the securing screws 38 with longitudinally extending passageiyays through which the water pipes 39' pass. wiresl lO pass through the passageways throughlwhich oif'lthe movable section-- may be heated in the; same manner that the bars of; the stationary sectionam heated. In order to support the-bars, 35

there are provided trusses through under cut slots formed transversely in the bars 35 and have their outer ds connected with the brackets 15 which the supporting wheels 14:. The webs 42 of the trusses all are provided with cut cuts through which the pipe 43 passes, the forward end of the pipe l3 being connected with the cross head 4%. This cross head 44 is connected with the pipes 39 by the nipples or'branches l5 and has one end portion -16 bent to permit the cross head i4: to' communicate with the interior of the hollow roller 47. This roller 47 is rotatably mounted by means of brackets 48 and rests upon the spacing strips 26 while the movable section is moving across the stationary section. A pipe 49 leads from the opposite end of the roller 47 and is connected with a cross head 50 with which the pipes 39 are connected as shown in. Figs. 1 and 2. Pipes 51 and 52 lead from the pipe 43 and cross head 50 respectively and telescope in the pivotally mounted sections 34 of pipes 32 and 33 so that when the movable section moves longitudinally the pipes 51 and 52 may slide in the sections 34: of pipes 32 and 33 and move pivotally with respect to pipe 43 and cross head 50 and thus not interfere with the sliding movement of movable section 16.

In the operationof this device the melted glass is placed upon the stationary section, the current having been first turned on so that it may pass through the wires to heat the water in the pipes and heat the sections and the movable section is then moved across the stationary section so that the roller which rests upon the strips 26 will roll the glassinto a plate. The treads 13 of the rails 11 are provided with cut outs so that when the roller has passed over the stationary section the supporting wheels may move into these depressions thus permitting the movable section to drop upon the strips 26 and compress the glass to expel all of the air from the glass. After the movable section has dropped upon the strips 26 the electric current is cut off and the water in the pipes will then gradually cool and as it cools-take up the heat from the bars forming the two sections thus causing the sections to gradually eool and cause the plate of glass to be properly annealed. After the plate of glass has cooled the movable sectionisreturned to the position shown in Fig. 1 and the table is then ready for forming a new plate of glass. The glass can therefore be rolled into a plate by the roller 17 and the rolled glass then compressed while still hot and then gradu-v ally' cooled,.the cooling while under compression causing all of the air to be expelled from the glass and the glass properly annealed.
